or DAYTON, OHIO rnnvrme MECHANISM Application "filed September21, 1927. Serial No. 220,901.

This invention relates to an improved printingmechanis'm. Oneof the principal objects thereof is to provide a printing mechanism to'make impressions or records from movable type, such as type wheels.

' 'Theconstruction described herein is capable of being used in connection with many and varied types of machines but'is particularly designed to transfer the records on movable counting wheels to a record strip which may be used by the auditor in checking accounts. In the particular construction shown in'thisapplication there are revoluble counting wheels, which record the number of tickets. sold to various destinations. It is necessary that records be made from these counting wheels for the auditors ofiice and this invention relates to .the particular machine for accomplishing this purpose. It is obvious. however, that it may be used for many other purposes and I, therefore, do not limit myself to the particular use described above butdesire to claimthe printing mechanism broadly regardless of what kind of record it may take. V In the drawings. Fig. 1 is a side elevational view of the. machine showing it in position on tracks to guide it and press it against the type Wheels. I I i Fig. 2.'is a cross sectional elevational view on the -line-22 of Fig. 1. I Fig.3 is a cross sectional elevational view onthe line 33 of Fig. 2.

Fig. 4: is a bottom plan view of the left- 35 hand portion of the carrier shown in Fig. 1.

Fig.5 is a fragmentary plan view of the means to hold the record paper at the end ofthe trackway, and p t Fig. 6 is a representation of a fragment of the record taken by the machine.

Referring'more particularly to the drawings" there are groups of type wheels 1 which are connected to the machine which issues tickets to'various destinations. Each time a 4 5 ticket is issued the group of counting wheels 1 corresponding to the station of destination is actuated one unit. If, for instance, New York is stationNo. 39 thenumber of tickets sold in any-particular interval of time to such destination can bereadily ascertained by subagainst thetype wheels so as to make a tracting the number appearing on the type wheels 1 corresponding to such station when the agentwent on duty from the number appearing on the same group oftype wheels when he went off duty. It is convenient, how ever, for the auditor. to have the numbers appearing on the various groups of type wheels transferred to a paper record instead of reading the record directly from the type wheels. By having such a record, it can be filed and referred to whenever necessary but if it were necessary for him to read this data from the type wheels the record. would be destroyed as soon as the machine was again actuated. The method I of actuating these type wheels and whatthey may register forms no part of this invention. The above statements are made by way of explanation ofthe mechanism with which this invention is related. I

On each side of the typewheels 1 are trackways 2 and 3 and above these trackways are upper trackways a and 5. .If desirable, the trackways may be adjustable toward and from each other by means of set screws 6, there being a-spring 7 interposed between the setscrews 6 and the upper rail. Channels 8 areprovided between the upper and lower trackways, which channels receive 1 bars 9 which are beveled as indicated by the reference character 10. These bars extend across the bottom of the carrier 11 and serve toguide and press the platen hereinafter described printed record. The carrier 11 consists of sidewalls 12 and 13 and a cover 14, which cover 14' extends up one side, over thetop and down the other side of the carrier, as clearly shown in Fig. 1.- Within the carrier is a plate 15;which carries a shaft'16. The sidewall 12 is formed integral with a hub 17 having a head 18. A circular plate 19 is provided with a journal 20 surrounding the hub 17 anda spring 21 resiliently presses the plate 19 against a roll of paper 22 journaled on the screws on the outer threaded portion of the shaft 16.

At the bottom of the carrier a wall 24 is secured to the plate 15by means of studs 25. Shafts 26, 27 and 28 are mounted in the wall 24: andplate 15. The shaft 26 carries an inking' roller 29; The shaft 27' carriesa resilient platen such as a rubber roller 30. Ifdesircd, a roller 31 may be inserted on the shaft 28. This latter roller, however, has not been found to be essential. A guard 32 may be provided to keep thepaper strip 011% the roll- 22 from coming into contact with the ink roller 29 and a guard 33"may beprovidedtoi act as a. brake on the roller 31 to prevent the paper beingfwithdrawn into the carrier. For convenience sake, the handle 34 isa't-tachedto the carrier by which it may be moved. .The endsof the trackways 2 and 3 are provided with acr'ossbar 35 to-whichis pivoted aholdingmember 36 provided with teeth In operation, the carrier is placed atthe end of the rails so that the bars Q'aredirected into-the channels 8. The paper passes down from the roll 22 beneath the rubber roller 3O and. over the roller 31 The projecting end is placed 011 the cross bar 35 and theho'lding member 36 is moved against it so that the teeth 3? pusli'through the paper and? hold it. The, carrier is now pulled forward either by grasping the carrier as a: unit or by pulling it by its handle 34 and as itmoves forwardthe paper is unwound fromthe roll 22 and is pressed against the" type wheels 1 by means of the rubber roller 30, the type wheel's'having been inked by the ink roller 29% The paper is then lifted from the type wheels by means of the roller 31 from whence it passes out ofthe carrier. When the cair'rier'has been moved to the end of the rails the paper now extends" for theentire length thereof and over all of" the type wheels. The paper is now brought against a knife edge 38* which may be serrated if desiredt'o' facilitate the detachment of't'he paper. The paper strip such'a's shown in 6-, having the recordiinpressed thereon, may now be lifted from between the trackways and when the holding member 36 is moved outwardly disengaging'the teeth 37 the" record strip may be turned over'to the auditor.

The'record' strip shown in Fig. 6'indioates that 6,572 tickets have been sold to; station No.

36 and that 8,960 have been sold to station No. 37, etc. for the remaining number's appearing thereon. Obviously, many changes may be made inthe machine without departing from the spirit or scope of this-invention. For instance, the thumb screws 6 and spring? may be dispensed witln Similarly, theguard 33 is not absolutely required nor is a roller 31 really necessary as there is very slight tend; ency of the paper to draw backwards into the carrier;- I, therefore, desire-to claim the in vention broadly except as I may limit myself in the appended claims. 1

I claim: 1. In combination with type members, a movable printing carrier, means for supporting a supply roll of paper, an inking member and" a platen carried by said carrier, and means whereby said carrier is guided so as to cause the paper from. said roll. to be pressed. resiliently" against said type member's after from said roll, and meanst'o directthe travel of said carrier and to force Saidsemndmem tioned means into resilient contact with said type members.

3. In combination with type members,- a movable print'ingcarrier, means for supporting a supply roll' of paperbarried thereby, means whereby said type members are inked, means whereby an impression from said't ype members is thereafter made on the paper from said roll, andnieans whereby said paper after being printed is lifted out of contact with the type members. i
